Does that mean Amazon has a lease from ARIN on those batches of IPv4 addresses for a period of time (in the same sense as a domain registry for x years) or actually own them?

Also, That Wikipedia article was particularly helpful. I knew the /32 was specific to my IP that I use but didn't realize the sheer scale of those blocks.

IP Address purchases one-time purchases, you don't pay annual fees.

There is another comment here that said Amazon paid ~18/IP. They won't pay this next year.
